CLOSET-FLUSHING TANK.

Application filed February 25, 1927. Serial No. 170,839.

The object of this invention is to provide an improved flushing tanlrof simple and- Figure 1 is a top plan view with the lid removed showing the operating parts'of the invention. Fig. 2 is a vertical section on the line TIII Fig. 1.

In the views 5 designates the box or casing and 6 a cover. The box has an outlet to the closet bowl at 5- 7 designates" a shell of a form resembling that of a gastropod moditied, it having an inlet vent at 8, said shell being pivoted to the walls of the box on trunnions 9 at the opposite faces of the shell so as to be out of balance: to turn to upright position whenemptied'of water, and also to be out of balance to tilt to discharging position when full of Water and released. The shell has a full transverse discharge at 10, and a transverse damming plate at 11 lightly oilset at its left hand edge from the wall of the shell so as to leave a vent at 12 of smaller capacity than the main discharge at 10. Formed within the rear right hand corner of the shell is an impact member or small pocket 13 of nearly the depth of the shell, it being adapted to overflow at its upper end into the main cavity of the shell and also adapted to discharge into said cavity when the shell is rocked to discharging position.

At 14 is a pipe for the water supply, under suitable pressure, said pipe entering the box and provided with a rotary, valve (not shown) in the casing at 15, it being of ordinary form but having connected with its stem a rod 16 carrying a float 17. The character 14 designates an extension of the supply pipe 14 beyond the valve in casing 15, said extension being curved at its end so that its discharge is directed into the pocket in all positions thereof as indicated by full and broken lines Fig. 2. The valve at 15 is arranged to turn on the water when the float 17 is down and to shut oif the same when the shell has been fully supplied.

At 18 is an ordinary spring actuated latching pin extending through the wall of the box in such position that its inner end engages the end of a spring 19 to prevent the shell fro-1n tilting to flushing position until digitally withdrawn. The spring 19 is'of a form of arrangement to pass up beyond the end of the latching pin 18 to shell-retaining position after the shell has been emptied and returned to upright or normal position. The valve case 15 acts as a stop to prevent the shell from tilting too far to the right or i clockwise after the return of theshell to filling position.

The operation which can be readily gathered from the foregoing is as follows:- Assuming that the shell is filled :and ready for the flushing operation the pin 18 is drawn out to release the shell, it tilting anti-clockwise to the position shown by broken lines Fig. 2. In this tilted .position the greater portion of the water inthe main part of the shell rapidly flows through the outlet 10 the discharge of the main portion being completed before all the dammed water is discharged thus leaving a sufficiency of the dammed water to supply the bowl after the main or flushingdischarge. The dammed water also maintains the shell in said tilted position for a short interval but when such dammed Water is about finally discharged the jet of water from the pipe 14, acting in the pocket urges the shell to its normal and latched position. The water from the pipe 14* ultimately fills the pocket and shell, the rising water in the shell causing meanwhile the rise of the float until the supply from said pipe is cut off by the closing of the valve. It will be observed,

therefore, that after the release of the latching pinv the operation of flushing, the return of the shell to normal position, the renewal of the supply and the shutting off of the supply are entirely automatic.

The forms of the parts can be changed without departing from the gist of the invention as claimed.

What I claim is:

1. A closet bowl flushing deviceincluding a box having an outlet, a, shell having a mouth leading volutely to a closed cavity above the plane of said mouth when in normal horizontal position, said shell being laterally pivoted in the walls of the box so as to be out of balance when filled with water to discharge by gravity when released from normal position, and also out of balance to return to normal position when emptied of water, means forautomatically supplying water to said shell when emptied. means for automatically latching said shell upon its return to normal'position, and means to release said latch at will.

2. A closet bowl flushing device including a box having an outlet, a shell having a mouth leading volutely to a closed cavity above the plane of the mouth when in normal position said shell being laterally pivoted in the walls of the box so as to be out Of balance when filled and also out of balance to turn to normal position when emptied of water, means for automatically latching the shell in normal or filled position, a damming member in said cavity, means for automatically supplying water to said inlet when the shell has been emptied, an impact member in said shell on which the water supply operates and means for controlling said supply of water.

3. A closet bowl flushing device including a box having an outlet, a shell having a mouth leading volutely to a closed cavity above the plane of the mouth when in normal position, said shell being laterally pivoted in the walls of the box so as to be out of balance when filled with water and also out of balance to turn to normal position when emptied of water, mean for automatically latching the shell in normal or filled position, and a damming member in said cavity adapted to retard the discharge of a portion of water from said shell.

4. A closet bowl flushing device including a box having an outlet, a shell having a mouth leading volutely to a closed cavity above the plane of the mouth when in normal position, said shell being laterally pivoted in, the walls of the box so as to out of balance when filled with water and also out of balance to turn to normal position when emptied of water, means for automatically latching the shell in normal or filled posi tion, means for automatically supplying water to said inlet when the shell has been emptiechmeans for controlling said supply of water, and a pocket in said shell opening near the mouth of the shell into: which the Water supply primarily enters.

5. A closet bowl flushing device including a box having an outlet, a shell having a the water supply primarily discharges to urge the shell to normal position;
